Ingredients Method Notes

Ingredients
  

For the brine
  • 1 cup apple cider vinegar Adds tanginess and depth of flavor.
  • 1 cup filtered water Helps dilute the vinegar.
  • 1 tbsp sea salt Enhances flavors and aids in pickling.
  • 1 tbsp sugar Balances vinegar acidity.
  • 1 tsp peppercorns Infuses a fragrant spice in the brine.
For the onions
  • 2 cups sliced red onions Provides sweetness and crisp texture.
  • 1 lime sliced Adds a refreshing twist.

Method
 

Preparation
  1. In a pot, add the apple cider vinegar, filtered water, sea salt, sugar, and peppercorns. Stir to combine.
  2. Heat the mixture over medium-high until it reaches a vigorous boil, about 2 minutes.
  3. Once boiling, add the sliced red onions and boil for 1 minute.
  4. Remove from heat and let cool for 1 minute before transferring to a mason jar, ensuring the onions are submerged.
  5. Insert lime slices into the jar and give it a gentle swirl to combine.
  6. Let the mixture cool to room temperature, serve immediately or let sit for a few hours or ideally 3 days for richer flavor.
  7. Screw on the lid tightly and store in the refrigerator. They will last several weeks.

Notes

Use thinly sliced onions for best results. A mandoline can ensure uniform slices. Customize by adding fresh herbs or other spices; adjust sugar for desired sweetness level.
